Nitrogen (N) is an important component of the forest soils and plays a pivotal role in ecosystem’s health, also broadleaf Moso bamboo ( Phyllostachys edulis ) forests. numerous functions production transformation soil organic matter (SOM) alterations soil’s physicochemical biological properties. Despite extensive research on properties microorganism diversity forests, we still know very little about N dynamics its significance or how various physical environmental variables influence physicochemical, dynamics, attributes. This article provides thorough overview forests changes processes by summarizing recent advances our knowledge microbial diversity, carbon (C) sink As are sensitive to change, even small change these ecosystems can alter overall dynamics. Here, dissect ecology provide insights into possibilities consequences future studies ecosystems.

Exogenous Putrescine Increases Heat Tolerance in Tomato Seedlings by Regulating Chlorophyll Metabolism and Enhancing Antioxidant Defense Efficiency

Plants, Год журнала: 2022, Номер 11(8), С. 1038 - 1038

Crops around the world are facing a diversity of environmental problems, which high temperatures proving to be most serious threat crops. Polyamine putrescine (Put) acts as master growth regulator that contributes optimal plant and development increased stress tolerance. Here, current study aimed elucidate how Put functions in regulating chlorophyll (Chl) metabolism, oxidative stress, antioxidant defense, well characterize expression genes related heat tomato seedlings under such stress. The results revealed treatment significantly attenuates heat-induced damage by promoting biomass production, increasing photosynthetic efficiency, inhibiting excessive production markers. Heat markedly decreased Chl content leaf accelerated yellowing process. However, Put-treated showed higher content, could associated with elevating PBGD activity (Chl biosynthesis enzyme) suppressing catabolic enzyme (Chlase MDCase). Under high-temperature levels gene encoding factors involved catabolism were down- upregulated, respectively, this trend was reversed heat-stressed seedlings. In addition, exogenous application boosted enzymes, along their genes, only plants stressed. Furthermore, heat-shock-related (HSP90, HSP70, HsfA1) elevated Put-treated, high-temperature-stressed Taken together, our indicate increases tolerance seedlings, concentrations activity, modulating endogenous free PA defense upregulating genes.

Straw incorporation serves as an effective strategy to enhance soil fertility and microbial biomass carbon (SMBC), which in turn improves maize yield agricultural sustainability. However, our understanding of nitrogen (N) fertilization straw into microenvironment is still evolving. This study explored the impact six N rates (N0, N100, N150, N200, N250, N300) with without on fertility, SMBC, enzyme activities, yield. Results showed that both management significantly affected organic (SOC), total N, Specifically, N250 treatment combined increased SOC, SMBC compared lower rates. Additionally, activities such urease, cellulase, sucrose, catalase, acid phosphatase reached their peak during V6 growth stage N200 under for conditions. Compared N300 treatments traditional planting, residue by 8.30 4.22%, respectively. All measured parameters, except cellulase activity, were higher spring than autumn across years, notable increases observed 2021. These findings suggest optimal levels (STN), along crucial sustaining enhancing grain treatments.

Abstract The current study aimed to investigate biofortification of maize grown under different irrigation intervals, i.e. 15, 20 and 25 days (hereinafter referred as IR15, IR20 IR25, respectively), using foliar application treatments (silicon (Si), zinc (Zn), silver nanoparticles (AgNPs), Si + Zn, AgNPs, Zn AgNPs AgNPs) in two growing seasons, 2020 2021. A split-plot design with four replications was used, where intervals were assigned main plots subplots, respectively. IR15 received a total 7925 m 3 /ha water divided over seven irrigations, while 5690 five irrigations IR25 4564 irrigations. highest yield grain quality observed plants irrigated at 15-day intervals. Spraying the canopy Si, either individually or combination, reduced negative impact stress caused by longer on plant growth, yield, components protein content. In most studied parameters, except for proline content, showed high positive impact, especially 100-kernel weight (KW). contrast, effects contents but harvest index. Collectively, resulted values all followed Zn. conclusion, our results suggest that an interval 15 combined has potential improve deficit stress.

AbstractModern agriculture has a major impact on natural resources in terms of exploitation and use. Land water are being exploited by ever-increasing population pressures. High nutritional inputs such as mineral nitrogen (N) fertilization required to achieve higher sustainable yields. Although crop production depends N fertilizers, the excessive inefficient use is worldwide issue that increases costs pollutes environment. Strategies increase efficiency (NUE) would be key reducing these negative impacts improved agronomic practices. To develop effective management approaches, it helpful understand effect various aspects growth, development, physiological processes crops. In this review, we highlighted recent progress made improve NUE adopting primarily practices may more environmentally economically beneficial, including site-specific-nitrogen management, enhanced fertilizer resources, conservation drip fertigation, modeling, precision agriculture. The first section discusses morphological effects crops while second section, strategies for growing with discussed.Keywords: Agronomic managementconservation agriculturecrop modelingnitrogen efficiencyprecision agriculturesustainability Disclosure statementNo potential conflict interest was reported authors.

Integrating Biofertilizers with Organic Fertilizers Enhances Photosynthetic Efficiency and Upregulates Chlorophyll-Related Gene Expression in Rice

Sustainability, Год журнала: 2024, Номер 16(21), С. 9297 - 9297

Опубликована: Окт. 25, 2024

Biofertilizers offer a sustainable method for improving rice growth and productivity, yet their effects on the interaction between plant growth, photosynthetic activity, gene expression remain under-researched. This study examines how biofertilizer influences physiology, focusing regulation of chlorophyll-related genes. Eight fertilizer treatments were applied: control (CNT), (BF), deactivated (DABF), straw (RS), with (RS+BF), organic (OF), (OF+BF), inorganic (IOF). Plant height, tiller number, SPAD, NDVI, chlorophyll content, photosynthesis rates measured, while analysis was conducted using RT-qPCR. The OF+BF treatment produced most significant results, leading to 31% increase in 135% 42% content (SPAD values) compared control. Additionally, enhanced efficiency by 74%, highest net rate 48.23 μmol CO2 m−2 s−1. Gene revealed that upregulated key photosynthesis-related genes, such as OsChlD OsCHLM, showing 70% 90% expression. These findings highlight potential integrating biofertilizers fertilizers sustainably boost contributing global food security climate change mitigation.
